Natsuho was kidnapped by a creepy man, Kunihiko. What I was waiting for was the days when I was humiliated as a model for a painting by Kunihiko's sister, Toyoko. Kunihiko takes care of Natsuho as if he were a puppet of Toyoko. If you don't listen to what you say, you will be broken ... Natsuho has no choice but to respond to Toyoko's escalating demands. After the fact, Natsuho gradually has warm feelings for Kunihiko, who cares for her like labor.
